A postdoctoral fellowship for an experimental physicist is now available in the Nano- and Quantum Electronics group at the Department of Physics of the University of Basel: www.nanoelectronics.ch The current project is strongly motivated by the recent excitement about topological phases and Majorana bound states that can appear in hybrid devices in low dimensions, for example in semiconducting nanowires with strong spin-orbit coupling, coupled to superconducting contacts. The combination of time-reversal symmetry breaking, spin-orbit field and superconducting pairing can give rise to new states of matter with non-trivial topological phases and unconventional pairing (triplet and p-wave). To unravel the emergence of Majorana bound states in single and coupled nanowires (NWs), we develop new probes with which the proximity gap and proximity-induced bound states (Andreev-, Shiba states) can be tested. Our approach is based on measuring both DC and AC transport, the latter at GHz frequencies using reflectometry. We are also able to measure microwave radiation in the GHz domain emitted by the quantum device using transmission line resonate circuits providing a deeper insight in charge transport through the evaluation of higher moments, such as shot noise. Within the current project we will use circuit QED techniques with tailored LC resonators to study nanowire hybrid devices in the strong coupling regime.

Your position Fabricate state-of-the-art devices that consist of semiconducting NWs with superconducting contacts. Do low temperature transport experiment and study the emergent bound-states induced by the pairing interaction using novel low and high-frequency probes. Work together with PhD students and other postdocs in a team.
Your profile We look for a highly motivated researcher who would like to explore fundamental aspects of quantum devices. You should have a dedication for experimental work in the field of quantum science and technology and be ready to collaborate and share your knowledge and experience in a team. We expect a strong dedication and commitment to push the frontiers of experimental physics. Requirement: The successful candidate should have a PhD in physics and be, if possible, experienced with GHz experiments, with low temperature systems, in particular dilution refrigerators, transport measurements of nanoelectronic devices, and nanofabrication technology.
We offer you We offer state-of-the art infrastructure, an initial funding period of two years with the possibility of a further extension. We offer a competitive salary.
